10. Consider Cell B, which is a normal neuron(i.e. one with standard extra- and intracellular concentrations ofmost ion species). a) Plot membrane potential vstime for the postsynaptic response of Cell B in response to aninhibitory neurotransmitter being released onto it by another cell,Cell A. Label and number axes. b) Explain how thiscould result by the neurotransmitter affecting EITHER an anionchannel or a cation channel on Cell B. c) Whatwould be the change of the postsynaptic potential of Cell B if youwere to instantly depolarize the presynaptic cell (cell A) fromresting potential to a membrane potential value exactly equal toE_Ca++? (the Nernst potential for calcium)
